Product overview

Released on November 25, 2019, the Ryzen Threadripper 3970X is a 3rd‑gen Threadripper (“Castle Peak”) built on AMD’s Zen 2 7 nm core. It pairs 32 cores and 64 threads with 3.7/4.5 GHz base/boost on the sTRX4/TRX40 platform, supporting quad‑channel DDR4 and PCIe 4.0. A discrete GPU is required (no integrated graphics).

Positioned as a workstation‑tier HEDT CPU, it exists for creators who need many cores, memory bandwidth, and expansion. It’s well‑suited to heavy video editing, 3D rendering, and streaming alongside general office/productivity. TRX40 boards expose up to 88 total PCIe 4.0 lanes for multiple NVMe drives and GPUs. Unique note: unlocked multiplier.
